ah , ok was this "NOTE : OEM Key given for Win 7 ultimate here is only of English US Language Install with other languages MUI. Wait for Oct 22 for specific language version when other OEM key will be leaked. " what confused me
AFAIK any key (OEM nor retail) is not country or language locked. You can also use the same key for the 32bit or the 64bit edition. Upgrade keys (they are most cheaper than normal retail keys) can also be used for a clean install but this is a little bit tricky because Windows 7 won't accept them during install.
Thanks Windows says that is activated , so i will activate windows updates ( i deactivated them because of wat)
